怎么開通企業付款到零錢？
有的商戶號的產品中心是沒有這個功能的，不過，該功能的pid（product id）是5，只要隨便進去某一個產品，在地址欄把pid改為5。
即可進入該功能頁面，進行開通，不過要滿足條件。
用戶提現代碼：
//用戶微信提現 private function withdrawals_weixin($id){ $falg = M('withdrawals')->where(['id'=>$id])->find(); $openid = M('users')->where('user_id', $falg['user_id'])->value('openid'); $data['openid'] = $openid; $data['pay_code'] = $falg['id'].$falg['user_id']; $data['desc'] = '提現ID'.$falg['id']; if($falg['taxfee'] >= $falg['money']){ return array('status'=>1, 'msg'=>"提現額度必須大于手續費！" ); }else{ $data['money'] = bcsub($falg['money'], $falg['taxfee'], 2); } include_once PLUGIN_PATH . "payment/weixin/weixin.class.php"; $weixin_obj = new /weixin(); $result = $weixin_obj->transfer($data); return $result; }其中pay_code在商戶號的提現功能是唯一的，所以為了防重放攻擊，這個值千萬不能用隨機數，最好用ID，具有提現記錄唯一。
提現邏輯代碼：
// 微信提現轉賬 function transfer($data){ header("Content-type: text/html; charset=utf-8"); //CA證書及支付信息 $wxchat['appid'] = WxPayConfig::$appid; $wxchat['mchid'] = WxPayConfig::$mchid; $wxchat['api_cert'] = PLUGIN_PATH.'/payment/weixin/cert/apiclient_cert.pem'; $wxchat['api_key'] = PLUGIN_PATH.'/payment/weixin/cert/apiclient_key.pem'; // $wxchat['api_ca'] = '/plugins/payment/weixin/cert/rootca.pem'; $webdata = array( 'mch_appid' => $wxchat['appid'], 'mchid' => $wxchat['mchid'], 'nonce_str' => md5(time()), //'device_info' => '1000', 'partner_trade_no'=> $data['pay_code'], //商戶訂單號，需要唯一 'openid' => $data['openid'],//轉賬用戶的openid 'check_name'=> 'NO_CHECK', //OPTION_CHECK不強制校驗真實姓名, FORCE_CHECK：強制 NO_CHECK： //'re_user_name' => 'jorsh', //收款人用戶姓名 'amount' => $data['money'] * 100, //付款金額單位為分 'desc' => $data['desc'], 'spbill_create_ip' => request()->ip(), ); foreach ($webdata as $k => $v) { $tarr[] =$k.'='.$v; } sort($tarr); $sign = implode($tarr, '&'); $sign .= '&key='.WxPayConfig::$key; $webdata['sign']=strtoupper(md5($sign)); $wget = $this->array2xml($webdata); $pay_url = 'https://api.mch.weixin.qq.com/mmpaymkttransfers/promotion/transfers'; $res = $this->http_post($pay_url, $wget, $wxchat); if(!$res){ return array('status'=>1, 'msg'=>"Can't connect the server" ); } $content = simplexml_load_string($res, 'SimpleXMLElement', LIBXML_NOCDATA); if(strval($content->return_code) == 'FAIL'){ return array('status'=>1, 'msg'=>strval($content->return_msg)); } if(strval($content->result_code) == 'FAIL'){ return array('status'=>1, 'msg'=>strval($content->err_code),':'.strval($content->err_code_des)); } $rdata = array( 'mch_appid' => strval($content->mch_appid), 'mchid' => strval($content->mchid), 'device_info' => strval($content->device_info), 'nonce_str' => strval($content->nonce_str), 'result_code' => strval($content->result_code), 'partner_trade_no' => strval($content->partner_trade_no), 'payment_no' => strval($content->payment_no), 'payment_time' => strval($content->payment_time), ); return $rdata; }其中 PLUGIN_PATH 是一個常量
define('PLUGIN_PATH', __DIR__ . '/plugins/');定義插件目錄
